The operating shaft 43 is driven from a drive shaft 49 by means of a pinion 50 carried on the drive shaft 49 and engaging a gear 51 carried on the operating shaft 43, and the drive shaft 50 is actuated in any suitable manner, as by means of an electric motor suitably connected thereto, not shown herein.

ltlounted upon the front upper corners of the frame side plates 31 and 32 is a fixed upper platen 52 adjustably secured in position by means of four supports 53 disposed it the four corners of the fixed platen 52 and each comprising a stud 54 provided at its lower end with a lower screw-threaded reduced extension 245 extending through a suitable aperture 246 in a boss 55 extending from the corresponding side plate 31 or 32, and at its upper end with an upper screwthreaded extension 247 extending through a suitable aperture 248 in a boss 56 extending from the corresponding corner of the fixed platen 52, a nut 57 engaging the lower reduced extension 245 to secure the stud 54 firmly in fixed position rising from the corresponding boss 55, and a pair of nuts 58 and 59 engaging the upper screw-threaded extension 247 of the stud 54 above and below the boss 56 extending from the fixed platen 52 to thus hold the fixed platen 52 firmly mounted at that elevation determined by the adjusted position of the upper and lower nuts 58 and 59 upon the upper extension 247. j Projecting from the right end of the fixed upper platen 52, bolted thereto, are a pair of arms 60 carrying horizontally alined inner and outer trunnions 61 and 62 rotatably supporting, respectively, a plain inner webguiding roller 63 and a taper-flanged outer web-guiding roller 64, carrying also a plate 294 supporting a weight 295 spaced from the plate 294 by the web and acting to impose tension upon the web therebeyond; extending from the lower portion of the outer face of the right side plate 32 are a pair of arms 65 carrying at their ends bearing boxes G6 in which are mounted anti-friction rollers 67 adapted to rotatably support the shaft 68 of the web roll 69; while extending from the upper portion of the outer face of the left frame side plate 31 are a pair of brackets 70 carrying web feeding and severing mechanism 71.

The web feeding mechanism herein shown comprises an upper roller 72 mounted upon a shaft 73 rotatably supported in supporting plates 74 rising from the brackets 70,

yupper roller 72 and and a lower roller 75 mounted upon a shaft 7 6 rotatably supported in a frame 77 pivoted at its upper end upon the shaft 73 of the upper roller 72 and having its lower end adjustably secured in position by means of links 78 pivoted at their outer ends to a cross shaft 79 mounted in the lower end of the frame 7 7 pivoted at their inner ends by pivot pins 249 to the free ends of arms 80 extending from a shaft 81 mounted in the supporting plates 74, and operable, to swing the arms 80, and reciprocate the links 78, and oscillate the frame 77, by means of a screw 82 rotatably and non-reciprocabljT mounted in a boss 83 projecting from one of the supporting plates 74, operable by means of a crank 84, and engaging within a correspondingly screw-threaded aperture traversing a lug 85 formed on the pivotpin 249 connecting that arm 80 with the corresponding link 78.

T he web is held in engagement with each of the upper and lower rollers 72 or 75 by means of two pairs of auxiliary rollers 86 each pressing one edge of the web against the corresponding upper or lower roller 72 or 75, and each rotatably mounted upon a pair of studs 87 projecting from a carrier plate 88 provided with a stud 89 by which it is in turn pivotally mounted upon an arm 90 secured, by means of a bolt 91 acting upon the split ends 92 of the hub of the arm 90, and in a desired adjusted position, on either the shaft 79 joining the lower ends of the frame 77 or on a shaft 93 connecting the upper extremities of the supporting plates 7 4; the lower roller 75 is operated from the upper roller 72 by means of an intermediate gear 94 carried by a shaft 95 rotatably mounted in the frame 77 and engaging cooperating gears 96 and 97 mounted respectively on the shafts 7 3 and 76 or the upper and lower rollers 72 and 75: and the upper roller 72 is operated, from a jack-shaft 98 driven from the operating shaft 43 by means of cooperating equal gears 99 and 100 carried respectively by the operating shaft 43 and the jack-shaft 98, by means of a rack 101 reciprocable in suitable guides 102 projecting from the corresponding supporting plate 74, co-acting with a pinion 103 rotatably mounted upon the shaft 73 of the carrying a dog 104 engaging a ratchet 105 fixed to the upperroller shaft 73, and operated by means of a link 106 connected to a crank-arm 107 secured to the left end of the jack-shaft 98 adjustable on the jack-shaft 98 by means of an adjusting screw 109 and to vary the throw, and held in adjusted position by means of a cap screw 108 entering the end of the jack-shaft 98 through a slot 254 in the crank-arm 107 and over-lying the two sides of the arm 107 to secure the arm 107 firmly to the end of the jack-shaft 98 in rthat adjustedl position' defined by'the@posi-A y Yends-with bearing tion of the adjusting screw 109 fand effective to produce that crank-throw'effecti-ng that extent of reciprocation of thel rack 101 which offthe'web; Y

The rack 136 is held in engagement with the gear 137 by means of a roller 269 pivoted upon a stud 270 projecting from the corresponding side plate 250 of the bed 35 and engaging the lower face of the rack 136.

Unser certain circumstances the movement produced by the substantially harmonic menen of the crank-arm 133 will maintain the impressing platen 124 substantially stationary over that period during which the forms 127 are in Contact with the web, but in order to insure that there is no recipriiifatory movement of the impressing platen 124 during that pe`iod l prefer to provide compensation for the impressing platen drive, and l therefore mount the shaft 133 in journals 141 reciproeable in slots 142 formed in the sides 250 of the bed 35, normally held lixecl against reciprocation in the slots 142 of the bed 35, but reciprocated during the time the form may be in Contact with the web the exact amount necessary to compensate for the slight reciprocation of the impressing platen 124 which may be produced by the cranlearm 133, thus to insure that the impressing platen 124 does not recipro cate to any extent whatever while the forms 127 may be in engagement with the web, the operating means for' the journals 141 of the shaft 138 b lng herein shown as comprisinglinlrs 143 terminating at 'their forward ends in collars 251 embracing the shaft 138 and having their rearward ends pivoted at 144 to arms 145 lixed to a shaft 146 mounted in the sides 250 of the bed 35 and provided with a bell-crank arni 147 pivoted at 143 to a link 149 which is guided at its lower end in any suitable manner, as by a fork (not shown) embracing the operating shaft 43, and is operated from a cani 150 carried by the operating shaft 43 by the action of the cam 150 upon a roller 266 carried by the link 149 adj acont the lower end thereof.

lVith this arrangement the iminobility of the impressing platen 124 may be additionally insured by the use of any suitable registering device interposed between the impressing platen 124 and the iixed upper platen 52, such as pins projecting from the upper fixed platen 52 in position to engage with registering apertures 253 in the impressing platen 124, and in such case I may dispense with any attempt to cause the compensating` mechanism to compensate exactly for the motion otherwise produced in the impressing platen 124 by the crank-arm 133, and may depend on the registering means alone to exactly register the two platens 124 and 52, and to hold the two platens 124 and 52 registered while the form may be in engagement with the web, and accordingly in such case l may utilize the compensating mechanism only to disable the normal drive .from the cranloarin 133 to permit the registering mechanism to operate.

1n the event that the press is being used only for embossing, so that inking is not required, l may disable the impressing-platen 4 reciprocating mechanism in any desired manner, as by disconnecting any two parts in the operating train, er by maintaining the linlr 149 in raised position, or otherwise.

Mounted upon the sides 250 of the bed by means of suitable bolts 262 are a pair of side brackets 151 supporting mechanism for inlzing the forms.

` Reciprocably mounted in the upper rear corners of these side brackets 151 is an oprod 152 provided at one end with a raclr section 153 engaginga gear 154 carried by a jaen-shaft 155 suitably supported from the corresponding side bracket 151 and operated by means of a second gear 156 actuated by a raclr 157 driven through a link 153 freni a lever 159 pivoted at 160 to the left side plate 31 and operated by means of a link 161 from a crank-arm 162 carried by the left end of the operating shaft 43 adjuste-,blo on the operating shaft 43 by means of an adjusting screw 163 and to vary the throw, and held in adjusted position by means of a :ip-screw 164 entering the end of the operating shaft 43 through a slot 255 u the crank-arm 162 and over-lying the sides or thecranlr-arm 162 to hold the crank-arm 162 firmly to the end of the shaft 43 in its adjusted position.

Mounted on the operating rod 152, secured thereto by means of machine-screws 165 to partake of the reciprocation of the operating rod 152, and additionally supported by a cross-rod 271 iixcd in the two side brackets 151 and extending there-between are a plu rality of platforms 166 each carrying secured thereto by suitable bolts 167 an ink-supply means 163 herein shown as comprising a reservoir 169 from which ink is delivered in substantially the usual manner by means ot an ink-delivery roller 170. Pivoted to each of these ink-supply means 163 is a frame 171 carrying at its free end a shaft 177 to which is iixed an intermediate roller 172 movable into an upper position engaging the ink-delivery roller 170, or into an intermediate free position, er down into position engaging the then upper face 263 of a polygonal intermediate bar 173 rotatably mounted in the side brackets 151; mounted upon the shaft 177 is a dog 174 engaging a ratchet 175 fixed to the shaft of the inkdelivery roller 17 0 and operating to advance the ink-delivery roller upon each move ment of the intermediate roller 17 2 into engagement with the i' lr-delivery roller 170; and rotatably mounted in bearing plates 258 carried on the outer end of the frame 171 are a pair of mixing rollers 176 engaging the intermediate roller 172 to mix the ink Cil '55." 170; that if the `control bar-178jis .now

To facilitate this rotation of the intermediate bar 173 the corners of the inter mediate bar 173 are chamfered, as shown at The transfer roller 203 is reciprocated in synchronism with the other mechanism of the press by means of a cam 207 mounted on the operating shaft 43 and engaging' a roller 208 carried by the lower end of a rink 209 guided at its lower end in any suitable manner, as by a guide link 272 pivoted to the right frame side plate 32 at 273, and secured at its upper end 210 to the arm 211 of a bellcrank lever 121 pivoted on the pivot shaft 36 of the bed 35 and provided with. a second arm 213 to which is pivoted at 214 a link 215 pivoted at its other end at 216 to an arm 217 secured by means of a hub clamp 218 in the desired adjusted position upona shaft 219 mounted in the side brackets 151 and carrying a pair of sectors 220 engaging racks 221 formed on the lower faces of the slides 201; while the mechanism for actually applying the ink to the forms after it has been supplied to the receiving roller 204 by the transfer roller 203 comprises three alined form-engaging rollers, a first form-engaging roller 222 directly engaging the receiving roller 204, and a second ferm engaging roller 223 and a third form-engaging roller 224 both engaging a carrier roller 225 receiving ink from the receiving roller 204 through a supplemental roller 226. The form-engag ing rollers 222 and 223 and 224 are mounted upon shafts 227 the ends of which are received in bearing blocks 223 adjustably secured, by means of machine-screws 229 passn ing through slots 265 in the bearing blocks 228, to supporting plates 230 receiving the machine-screws 229 and themselves supported by means of studs 231 from the side brackets 151, and adjusted to that position effective to secure the form-engaging rollers 222 and 223 and 224 at the proper level to .roll over the top of' the forms as the forms are drawn under these form-engaging rollers upon retraction and subsequent advance of the impressing platen 124; the supplemental roller 226 is mounted upon a shaft 232 supported in bearing plates 233 rising from the side brackets 151; and the carrier roller 225 and receiving roller 204 are mounted on shafts 234 and 259 rotating in bearing apertures 235 and 260 in the side brackets 151 and carrying pinions 236 and 261 meshing with a gear 237 which is rotatably mounted upon a stud 238 fixed in the corresponding bearing plate 230.and is operated by engagement with a rack 239 carried by the upper face of one side of the impressing platen 124 and operated to effect rotation of the various rollers as the impressing platen 124, and the forms carried thereby, are retracted and advanced beneath the form-inking rollers 222 and 223 and 224.

It will of course be understood by those skilled in the art that l may apply any desired number of ink-supply means 168, and at any desired spacing along the ink-supply means operating rod 152, and that may adjust the drive for the ink-supply means operating rod 152 to reciprocate the inksupply means 163 to any desired eX- tent, and accordingly that I may so adjust the mechanism that each ink-supply means 163 will apply ink to any desired portion of the intermediate bar 173, including a condition whereby one or all of the ink-supply means 163 applies ink to the intermediate bar 173 right up to the point at which the adjacent ink-supply means 168 has applied ink to the intermediate bar 173; also that the various ink-supply means 163 may apply ink of different characteristics, such as different colors; and in addition, that the transfer roller 203, and the various distributing rollers, transfer to every section of each form-inking roller 222 or 223 or 224 ink from the corresponding section of the intermediate bar 173, so that the formeinking rollers 222 and 223 and 224 apply ink across the forms at every point of exactly the characteristic of the ink at that point on the intermediate bar 173.

Under some circumstances it becomes desirable to restrict the quantity of ink applied. to a particular portion of the form, and with the mechanism herein shown I may achieve this result conveniently by covering part or all of the corresponding portion of the in'- termediate bar 173 by means of thin strips 240 held in adjusted position yby a clamping bar 241 adapted to be drawn by means of machine-screws 242 into position clamping the strips 240 between the clamping bar 241 and the upper face 242 of an angle bar 243 receiving the machine-screws 242 and itself secured to the side brackets 151 by suitable bolts 244.

It will of course be understood by those skilled in the art that the various parts of the press are all operated in concordance, that the Web is slackened during the final portion of the period over which the bed35 is retracted, and during the advance of the bed 35; that the web is fed intermediate the period during which the bed 35 is retracted; that the web is severed while the bed 35 is advanced to bring the impressing platen 124 into impressing relation with the fixed upper platen 52; that the impressing platen 124 is Withdrawn under the form-inking rollers 222 and 223 and 224, and these and the cooperating rollers actuated, and is then advanced, and the various rollers again i, italians# thethen lowerfface 263 of the intermediate bar 1.73 While the intermediate roller 172 isapplyiiigink to the then upper face 263 of the intermediate bar 17 3; that the intermediate roller 172 applies ink to the then upper face 263 of the intermediate bar r173 intermediate the period during Which the bed 35 u is in retracted' position, and Atherefore opcrates to receive the ink from the 'ink-delivery roller V170 just before the advance of the severing said' Weby transversely comprising a bed 35, and to mix the ink With the aid of the mixing rollers 176 during the balance of the period over Which the beoll 35 is in ref proved means for 'feeding the web, and new i ing the form.

tracted position, during the advance and retraction of the bed 35, and during the'iirst part of the succeeding retraction period of the bed 35; and that the intermediate bar 173 is rotated While theintermediate roller 172 is rising to receive the ink from the inkdelivery roller 170; and therefore just before the advance of the bed'35.

Fromy the above description it AWill be obviousV to those skilled in the art that I have provided a printing press embodying various improvements over the presses. heretofore known, particularly new` and iniand improved means for mounting and link- Under these circumstances it ,Will of course `be obvious to those' skilled iii'the art that the embodiment of myinvention herein shown and described accomplishes at least the principal objectief my invention.'

At the same time-it also lWill be obvious to those skilled in the artthat the embodiment of my inventionl herein shoWnand described embodies advantagesfotherthan those par-` ticularly pointed out and suggested herein, and also that lthis particular embodiment of my invention may be variously changed and modified Without 'departing from the spirit of my invention or sacrificing the advan tages thereof, and accordingly it Will be understood that the vdisclosure* herein `is illustrativeonly, and that my invention is ynot limitedthereto. i J
